Etymologies

a- (“without”) +‎ sexuality; asexual +‎ -ity (Wiktionary)

Examples

(And it’s rarely been used to refer to asexual people; most asexuals are either male or female, since asexuality is a sexual orientation, not a gender identity.) “It” is not an option, not because “it” does not have a tradition of application to humans, but because it DOES have a tradition of application to humans – ones the speaker wants to discount and marginalize.

If lack of desire for activities like that are the definition of "asexuality" used to come up with the 19% figure, well, that makes sense, but it actually has very little to do with sexual attraction per se, and everything to do with the circumstances surrounding it.

It doesn't imply a value judgement of the proclivity to admit candidly that these are deviancies, and so-called "asexuality" is even more deviant, even more fundamentally at odds with basic human norms far more so than the two just listed.
